An example of a conventional roller blind fabric mounting device is shown in FIG. 23 . On the upper end of the fabric 1 constituting the cord, a fabric hold-down plate 2 molded from synthetic resin is mounted, and the fabric hold-down plate 2 is snapped into a mounting recess 4 of the reel 3 .

Also, when the reel 3 is rotated, the screen is wound on the reel 3 or the screen is unwound from the reel 3, thereby raising or lowering the screen.

(About the counterweight bar for roller blinds)

For example, in the roller blind described in patent document 3, it is comprised so that a screen can be reversed (front and back reverse). By implementing different pattern designs on the front and back sides of the curtain, the user can select the pattern design of the curtain according to his/her preference.

Specifically, a pair of weight bars are provided on both ends of the curtain. The roll tube has a shaft core and a fitting portion surrounding the outer periphery of the shaft core. The cord is sandwiched between the fitting portion and the outer periphery of the shaft core in its thickness direction. In addition, a pair of fitting holes into which the weight rod can be fitted are formed in the fitting portion. In a state in which one weight rod is fitted into the corresponding fitting hole, one side of the screen is located on the indoor side. Then, while reversing the front and back of the screen, the weight bar in the fitting hole is pulled downward. In this way, the curtain passes between the shaft core and the fitting portion and is sent to the side of one weight bar. Then, the other weight rod is fitted into the corresponding fitting hole so that the other surface of the curtain is located on the indoor side.

For example, as shown in FIG. 43 , the roller blind described in Patent Document 5 includes: a roller tube 105 supported rotatably around an axis, a screen 100 attached to the roller tube 105 , and a lower end attached to the screen 100 . The counterweight bar 111. This weight bar 111 is configured so that a baffle plate 115 can be fitted in order to reduce contact with the frame when the screen is rolled up. That is, as shown enlarged in FIG. 43 , on the left side of the weight rod 111 is formed a fence side groove 116 into which the fence 115 fits. In addition, a screen-side groove 117 is formed on the upper side of the weight bar 111 .

Therefore, when the fitting direction of the fabric presser 2 with respect to the reel 3 is limited to one direction as described above and the fabric and the fabric presser are joined by sewing or the like, the fabric surface exposed inside the room cannot be changed. In addition, even if the surface of the material exposed to the inside of the room can be changed, it is necessary to untie the sewn part, turn the front and back of the material 1 over, and re-sew it on the material pressing plate 2, which requires extremely cumbersome work.

In the curtain attachment structure for a roller blind disclosed in Patent Document 1, a fitting portion that engages and accommodates an edge member for preventing the curtain from coming off is formed on the bottom surface of the support member. In this structure, since the edge member is not held in the fitting portion when the screen is attached, it is necessary to insert the supporting member into the mounting groove while holding the edge member in the fitting portion with fingertips.

And finally, it is impossible to confirm whether the edge member is held in the fitting portion when the supporting member is installed in the mounting groove, so that the supporting member cannot be reliably mounted in the state where the edge member is not held in the fitting portion. Install into the mounting slot. Therefore, there is a problem that the installation work becomes complicated.

Patent Document 2 discloses a roller blind in which the direction in which a support member is attached to a spool can be changed by providing locking pieces on both sides of a fitting protrusion. However, Patent Document 2 does not disclose a structure for changing the carcass surface exposed indoors.

Patent Documents 3 and 4 disclose a structure in which a screen can be changed by providing expanded portions at both ends of the screen so that the screen can slide relative to the roller tube and any one of the expanded portions is caught in the insertion portion. The positive and negative sides and support structure. However, since the stuck enlarged portion is not fixed on the coiled tube, there is a danger that the expanded portion may jump out of the coiled tube during normal use.

The object of the first aspect of the present invention is to provide a fabric mounting device for a roller blind that can securely fix the fabric to the reel during normal use and can easily change the fabric exposed to the indoor side. noodle.

That is, in the structure shown in FIG. 43 , the screen 100 is detached from the roll tube 105 . Then, the screen 100 is attached to the roll tube 105 again after the screen 100 is reversed. In this state, when the weight bar 111 is attached to the material pressing plate 110 in the same direction as above, the weight bar 111 comes into direct contact with the frame 120 when the screen 100 is rolled up. Therefore, as shown in FIG. 44 , it is necessary to insert the material pressing plate 110 into the weight bar 111 after turning the weight bar 111 in the left-right direction of this FIG. 44 . When inserted in this way, the left end portion of the material pressing plate 110 is pulled upward. At this time, there is no member that locks the material holding plate 110 like the above-mentioned locking portion 118 . Therefore, as shown by the dashed-two dotted line in this FIG. 44 , the weight bar 111 falls off from the material pressing plate 110 . In this way, the counterweight rod 111 with the baffle plate 115 and an asymmetric cross-section cannot cope with the inversion of the front and back of the curtain 100 .

The object of the second aspect of the present invention is to provide a weight bar that does not complicate the structure of the roller blind and that can be attached to the weight bar even if the front and back of the curtain are reversed relative to the weight bar. on the curtain.

This force is relatively applied by the gravitational force of the weight bar 40 and the weight 58 , and is not applied by actually pulling the screen 10 upward. At this time, one end side (the end opposite to the abutting portion 17 a ) of the lower side material holding plate 17 is locked by the first locking portion 46 via the screen 10 attached to the lower side material holding plate 17 . By doing so, the weight bar 40 does not fall off from the lower side material holding plate 17 due to the gravity of the weight bar 40 and the weight 58 .

(effect)

The action when the front and back of the screen 10 is reversed will be described. Here, first, the operation when the screen 10 is attached to the reel 13 when the screen 10 is turned over will be described.

As shown in FIG. 29 , first, the material holding member 31 is removed after the screen 10 hanging from the outdoor side of the reel 13 is brought into a state of hanging from the indoor side of the reel 13 . Then, as shown in FIG. 30 , the front and back of the screen 10 are turned over so that the upper side material holding plate 15 is located below the material and the screen 10 is located above the upper side material holding plate 15 . Next, as shown in FIG. 31 , the fitting groove 32 of the material holding member 31 is fitted into the enlarged diameter portion 19 of the locking protrusion 18 . Then, as shown in FIG. 32 , the screen 10 is suspended from the outdoor side of the reel 13 again to complete the inversion of the front and back of the screen 10 .

Next, the action when the weight bar 40 is attached when the screen 10 is turned over will be described. As explained above with reference to FIG. 28 , the baffle plate 50 mounted on the weight bar 40 suppresses the contact of the weight bar 40 with the frame 11 . In order to exhibit this function, it is necessary to make the baffle plate 50 exist on the outdoor side in the state where the weight bar 40 is attached to the screen 10 . Therefore, when the screen 10 is turned over, the weight bar 40 is also turned over.

As described above with reference to FIG. 33 , with the lower side material holding plate 17 locked by the first locking portion 46 , the lower side material holding plate 17 is pulled out from the side of the weight bar 40 . Then, the lower side material holding plate 17 is inserted into the weight bar 40 again in a state where the lower side material holding plate 17 is turned left and right along with the turning of the screen 10 . Then, as shown in FIG. 34 , the right end portion of the lower side material holding plate 17 is relatively pulled upward by the screen 10 .

At this time, the contact portion 17a contacts the curved surface 41a on the front wall 48 side, whereby the lower side material holding plate 17 assumes a stable posture. Then, one end side (end opposite to the contact portion 17 a ) of the lower side material holding plate 17 comes into contact with the second locking portion 47 via the screen 10 . The second locking portion 47 locks one end side of the lower side material holding plate 17 , thereby holding the lower side material holding plate 17 in the upper groove 41 . By doing so, the weight bar 40 does not fall off from the lower side material holding plate 17 due to the gravity of the weight bar 40 and the weight 58 .

According to the embodiment described above, the following effects can be exhibited.

(1) Even when the lower side material holding plate 17 is turned over as the front and back sides of the curtain 10 are turned over, the lower side material holding plate 17 is held in the upper groove 41 of the weight bar 40 . When the surface 10 a of the screen 10 is on the indoor side, the lower side material holding plate 17 is locked in the upper groove 41 by the first locking portion 46 . In addition, when the back surface 10b of the screen 10 is on the indoor side, the lower side material holding plate 17 is locked in the upper groove 41 by the second locking portion 47 . Therefore, it is suppressed that the weight bar 40 falls off from the screen 10 due to its own weight. According to this structure, even if it is a roller blind in which the front and back of the screen 10 can be reversed, it is sufficient to provide one weight bar 40 . Therefore, the weight bar 40 can be attached to the screen 10 without complicating the configuration of the screen 10 even if the front and back of the screen 10 are reversed.

(2) The second locking portion 47 is formed such that its rear side and upper side are covered by the baffle plate 50 attached thereto. That is, the second locking portion 47 is lower than the first locking portion 46 and is formed inside. By forming the second locking portion 47 in this way, the symmetry of the overall cross-sectional shape can be ensured when the baffle plate 50 is attached to the weight bar 40 . In this way, the weight balance and designability of the weight bar 40 in the state where the baffle 50 is attached can be improved.

(3) A pair of curved surfaces 41 a are formed in the upper groove 41 . This curved surface 41 a is formed in a shape matching the curved surface of the contact portion 17 a of the lower side material holding plate 17 . By doing so, in the state of FIG. 33 and FIG. 34 in which the screen 10 is turned over, the position which contacts the curved surface 41a in the contact part 17a can be fixed.

(Second embodiment of the second aspect of the present invention)

Hereinafter, a second embodiment of the second aspect of the present invention will be described with reference to FIGS. 35 and 36 . The roller blind of this embodiment has substantially the same configuration as the roller blind of the first embodiment except that the material thickness of the screen is different from that of the first embodiment. Hereinafter, differences from the first embodiment will be mainly described.

As shown in FIG. 35, the thinnest material for sewing is used for the cord 60 of this example. This screen 60 is the same as the above-mentioned embodiment, and the two material holding plates 15 and 17 are sewn to the screen 10 .

The inversion operation of the front and back (front and back) of the screen 60 is performed in the same manner as in the first embodiment described above. As shown in FIG. 35 , since the material of the cord 60 is thin, the lower side material pressing plate 17 is held at an angle corresponding to the difference in the thickness of the material after being rotated toward the clockwise direction as compared with FIG. 33 in the first embodiment. position. At this time, the contact portion 17a of the lower side material holding plate 17 abuts against the right curved surface 41a, thereby also stabilizing the position of the lower side material holding plate 17 .

Similarly, as shown in FIG. 36 , when the front and back sides of the screen 60 are reversed, the lower side material holding plate 17 is held at a counterclockwise rotation and a material thickness difference compared with FIG. 34 in the first embodiment. position after the corresponding angle. At this time, the contact portion 17 a of the lower side material holding plate 17 abuts against the left curved surface 41 a, thereby also stabilizing the position of the lower side material holding plate 17 . In other words, even if the angle at which the lower side material holding plate 17 is in a stable state differs due to changing the thickness of the cord, the lower side material holding plate 17 can be kept at a stable angle by forming the curved surface 41a. That is, the degree of freedom of rotation of the lower side material holding plate 17 is ensured by the curved surface 41a.

According to the embodiment described above, especially the following effects can be exhibited.

(4) Even when the thinnest fabric for sewing is used as the cord 60 , the lower side material holding plate 17 can be held by the same weight bar 40 as that of the first embodiment. In this way, the versatility of the weight bar 40 can be improved.

(Third embodiment of the second aspect of the present invention)

Hereinafter, a third embodiment of the second aspect of the present invention will be described with reference to FIGS. 37 and 38 .

Specifically, as shown in FIG. 37 , the abutting portions 15a and 17a provided on the material press plate for sewing are omitted, and the material press plate 62 is formed entirely in a plate shape. This is because, unlike sewing, mounting with a stapler can be done in one go, so that the fabric will not be misplaced. Furthermore, the fabric presser 62 is thinner than the fabric presser for sewing.

The inversion operation of the front and back of the screen 61 is performed in the same manner as in the two embodiments described above. As shown in FIG. 37 , since the material of the cord 61 is thick, the material pressing plate 62 is held at a position after being rotated counterclockwise by an angle corresponding to the difference in material thickness compared to FIG. 33 in the first embodiment. . At this time, the right end portion of the fabric presser 62 abuts against the right curved surface 41a, thereby also stabilizing the position of the fabric presser 62 .

Similarly, as shown in FIG. 38 , when the front and back sides of the screen 61 are reversed, the material pressing plate 62 is held to rotate clockwise corresponding to the difference in material thickness compared to FIG. 34 in the first embodiment. The position after the angle. At this time, the left end portion of the fabric presser 62 (more precisely, the end of the screen 61 ) abuts against the left curved surface 41 a, thereby also stabilizing the position of the fabric presser 62 . In other words, even when the angle at which the material holding plate 62 is in a stable state differs due to the change in the thickness of the cord, the forming of the curved surface 41a can maintain the material holding plate 62 at a stable angle.

According to the embodiment described above, especially the following effects can be exhibited.

(5), even if the cord 61 adopts the thickest fabric for the stapler, and further adopts the fabric pressing plate 62 for the stapler, it can be maintained by the same counterweight bar 40 as in the above-mentioned embodiments.

According to the embodiment described above, especially the following effects can be exhibited.

(6) Even when the thinnest material for a stapler is used for the fabric 65, the material pressing plate 62 can be held by the same weight bar 40 as in each of the above-mentioned embodiments. In this way, the versatility of the weight bar 40 can be improved.
